Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a stepwise driven conveyor device with means for arranging articles to be subjected to different operations, and a handling device for carrying out the operations to which the articles are subjected, e.g. The present invention relates to a manufacturing apparatus for manufacturing ice cream confectionery, such as ice cream cornet.

Manufacturing devices of the above type are known, and according to the conventional agglomeration, the different operating devices carry out their operations while the conveyor device is stationary. Therefore, the stop time of the conveyor device is determined by the operating device that takes a long operating time. As a result, the transit time of the article through the manufacturing equipment may become unnecessarily long. The reason for this is that operating devices with a short operating time are not activated during part of the period when the conveyor device is stationary.

It is an object of the present invention to provide a manufacturing device of the above type in which one or more operating devices require a relatively long period of time to carry out their operation, but which can be operated in a relatively short static +L time to increase productivity. Our goal is to provide the following. The purpose of this is that an operating device with a short operating time is arranged stationary along the conveyor device, and at least two operating devices with a long operating time are mounted movably along the conveyor device so as to move together with the conveyor device. However, this is achieved according to the invention in that the conveyor device performs one step and then moves by one step in the direction opposite to the direction of movement of the conveyor device. Therefore, the conveyor device remains stationary, i.e. An operating device with a long operating time during a period between steps can start operating, continue operating during the next step of the conveyor device, and then continue operating during the next stop period. Operating devices with relatively long operating times have to be doubled, but on the other hand the capacity of fixed operating devices has to be better utilized so that the total production star is increased.

According to a preferred embodiment of the invention, the at least two
The two operating devices can be arranged at a mutual spacing corresponding to one step or an unequal number of steps of the conveyor device. It is thus achieved that said at least two handling devices are able to process all articles conveyed by the conveyor device.

Furthermore, the at least two operating devices do not have to be arranged at a distance from each other corresponding to one step of the connecting device, which is sometimes difficult to implement. This is difficult to implement because such operating devices occupy so much space that it is impossible to arrange them with a mutual spacing corresponding to only one step of the conveyor device.

In particular, according to a simple embodiment of the production device according to the invention:
The conveyor device can consist of a linear conveyor.

Another embodiment of the manufacturing device according to the invention provides that the drive for the conveyor consists of a moment amplifier, and the drive for the movable handling device consists of a linear amplifier, said amplifier being arranged during the advancement step of the handling device and the conveyor. The conveyor and the movable operating device are synchronized for synchronous movement, and the amplifier is adjustable to adjust the speed and length of the stepped movement. Therefore, it is possible to employ movable operating devices and conveyor speed variations that allow the production device to operate optimally depending on the mulberry crop (applied to the article).

Furthermore, it is appropriate that the stop time of the amplifier is also adjustable.

This is because it becomes possible to match the manufacturing equipment to the fixed operating device that takes the longest operating time.

To provide the synchronization required by the amplifiers, each of the amplifiers
According to the invention, the stepper motor may be controlled by a corresponding stepper motor, and such stepper motor may be controlled by a microprocessor common to the stepper motors.

According to one embodiment of the invention, a longitudinally extending fixed beam and a longitudinally extending reciprocating beam are provided along one side of the conveyor apparatus in order to facilitate the replacement of individual operating devices of the manufacturing device due to the specific operations carried out by the operating devices. A dynamically movable sliding rond is provided and along the other side a longitudinally extending fixed sliding rod is provided, the fixed operating device being adapted to be fixed to the beam and the fixed sliding rod. However, the movable operating device is fixed to a movable sliding rod,
It can be arranged to be movably supported relative to a fixed sliding rod.

The present invention will be further described below with reference to the accompanying drawings.

The manufacturing device shown in FIGS. 1A and 1B includes a conveyor device 1 driven like a stepper motor, which according to the illustrated embodiment includes a conveyor that is moved in a linear manner. The conveyor includes an endless conveyor hand 2, which is stretched around end reversing rollers 3 and 4. According to the embodiment shown, the hand consists of a lamella 5 whose ends are pivotally connected to two endless tubes (not shown). These lamellas 5, which are not shown in detail in the figures, consist of narrow and extending metal strips transversely to the conveyor hand, the metal strips being spaced #L at small intervals.

The spacing between the lamellae, and therefore the pitch of the hand, is
It is indicated in the figure by a short line extending perpendicular to the hand.

The embodiment of the production apparatus shown in the figure is for producing ice cream confectionery in the form of an ice cream having a metal molding tool. Each laterally extending lamella thus includes an array of means for positioning articles undergoing various operations in the holes of the illustrated embodiment. The manufacturing apparatus shown for carrying out the said operations consists of a row of operating devices which, as seen from the left in FIGS. 1A and 1B, are connected to the following devices: A fixed operating device 7 for inserting a row of packaging cones in which conical wafers are arranged, an operating device 8 for controlling that each hole is provided with a cone;
and two identical mulberry making devices 9.10 for filling the wafer placed in the packaging cone, and the same operating device 11 for filling the ice cream 1 into the wafer.
．． 12, an operating device 13 for placing chocolate on the filled ice cream, an operating device 1.1 for scattering decoration materials, and an operating device 15 for providing a lid on the cone. It consists of an operating device 16 for closing the cone around the lid and a projection station 17, which will be described in detail below.

It will be understood that the operating device described above is mentioned by way of example only.

According to the embodiment shown, of the operating devices devices 7.8.13.14.15 and 16 are fixed, but two injection devices 9.10 and two filling devices 11
．． 12 is movable.

A reciprocating sliding rod 20 is provided along the side of the manufacturing equipment located on the observer side in FIGS. 1A and 1B, and this rod 20 is shaped like a linear amplifier in FIG. 1B. It is driven by an actuator or drive device 21. Furthermore, a fixed beam 23 is arranged along said side of the production device, as can be seen in FIGS. 2 and 3. A fixed sliding rod 24 extending longitudinally along the opposite side of the production equipment (see also FIGS. 2 and 3)
is located.

The role device 7 is supported by the compare frame J, 25 in the embodiment shown, while the identification devices 8.13.14.15 and 16 on one side are clamped, for example, to the beam 23 in FIG. FIG. 2 schematically shows one such fixed operating device, such as device 14. The fixed operating device is clamped on the other side to the fixed sliding rod 24.

Regarding the movable operating devices, one of them, 12, is shown schematically in FIG.

The movable device is clamped on one side by a movable sliding rod 20, while the other side is supported by a fixed sliding rod 24.

However, these movable operating devices are movably supported by ball sleeves, as indicated by numeral 25 in FIG.

It is thus understood that when the sliding rod 20 reciprocates in the longitudinal direction, the sliding rod 20 carries the devices 9, 10, 11 and 12, and during this movement these devices slide on the fixed sliding rod 25. It will be.

On the contrary, the fixing device is fixed in its position because it is fixed to the beam 23 and fixed sliding rond 24 as described above.

The projection station 17, which is shown in detail in FIGS. 5 and 6, is of a type known per se, so that it will suffice to say that it consists of a transversely extending beam 27 which is longitudinally reciprocatable. The cross beam 27 has a number of projectors 2 corresponding to the number of array means in each lamella.
It carries 8.

Each of the radiators 28 includes a block 29, on both sides of which guide pins 30.30 are fixed;
Each block is provided with an abutting portion 31. beam 2
7 is movable as shown by the double arrow 3 in FIG. The projection device is activated to project from the lamella 5 of the conveyor hand.

The conveyor of the manufacturing device is driven by an actuator 35 of FIG. 1B in the form of a Mont amplifier. The moment amplifier drives the end reversing roller 4 through a gear, shown schematically as a gearing 736, which drives the conveyor hand.

According to the embodiment shown, a linear amplifier known per se is used as the linear amplifier 21, which linear amplifier is commercially available, for example "Nis. It is commercially available as an "electro-hydraulic linear amplifier" from the company. Such a linear amplifier consists of a hydraulic piston-cylinder arrangement which is controlled by a microprocessor, 10 to a control chart 39, as shown in FIG.
It has a built-in hydraulic valve 37 which is driven by a step motor 38 via a step motor 38. Such linear amplifiers are known per se, so if you want to start this linear amplifier,
Is there a system to control the step motor from the micropro sensor 40? When ff1lchar 1.39 pulse is generated,
The stepper motor's output shaft rotates a predetermined angle in one direction or the other. The direction in which step motor 38 rotates is also controlled 411 by the microprocessor.

As mentioned above, the stepper motor 38 is connected to a hydraulic valve 27, said valve on the morph side controlling the linear amplifier 21 by directing fluid to one side or the other side of the piston of the piston-cylinder arrangement. drive The piston is provided with a thread into which a spindle engages, one end of which is connected to a hydraulic valve. Screw 1
- When the valve moves in one direction or the other, the spindle rotates so that the hydraulic valve is controlled in the opposite direction, thus closing when the hydraulic valve is closed, and thus stopping the drive of the piston. be done. For linear amplifiers, each pulse generated by the microprocessor achieves a well-defined longitudinal movement of the amplifier piston.

The moment amplifier 35 is also provided with a hydraulic valve 42,
This valve operates in the same way as the moment amplifier 35 given that it is controlled from the microprocessor 40 through the control chart 43 and stepper motor 44. In this case, the hydraulic valve controls the delivery of fluid to the hydraulic motor, which rotates a predetermined angle with each pulse generated by the microprocessor 40, as described above with respect to the linear amplifier. be done. This rotation angle is
is transmitted to the reversing roller 4 at the end via the chain 36,
Therefore, the conveyor hunt is driven.

As a result of the angle through which the moment amplifier 35 is rotated by each pulse received from the microprocessor due to the meshing of the chain 36, the conveyor hunt is moved, but this moving star is linear when the linear amplifier receives a pulse from the microprocessor. It corresponds to the displacement term applied to the movable sliding rod by the amplifier. Such a moment amplifier is commercially available from C.I.G. Schweitzer Lissochindustrie Gesellschaft under the name "Electrohydraulic Rotational Moment Amplifier".

Therefore, the movable actuator and conveyor band
The moment amplifier and the linear amplifier follow each other in being pulsed. The number of pulses generated by microprocessor 40 therefore determines the distance traveled by the hand and mobile device. Since the microprocessor can simultaneously reverse the direction of movement of the linear amplifier, it is possible to obtain the curves shown in FIG. 1 as a function of time for the movement of the conveyor/S throat and the movable device, respectively. The speed at which the conveyor hand and movable device move during a step can also be controlled by a microprocessor, such as by varying the frequency of the pulses generated during the step.

The movement of the conveyor band as a function of time is shown in FIG. 4 as a solid line, while the movement of the movable device as a function of time is shown as a dashed line. If time X7'l< has elapsed since time O, it can be seen that the movable device and hand are stationary. The movable devices and notes then move simultaneously with the same velocity change until they have moved by one step (corresponding to coordinate Z in FIG. 4).

During the next stop period, the moving 111 devices and nodes are stationary. During the next step movement, the hand moves one step in the previous movement direction until a new step corresponding to the coordinate Z is performed. At the same time, the movable device moves back to the starting position. The rope also moves one step in the direction opposite to the hunting direction corresponding to coordinate 0 in FIG.

FIG. 8 shows the manner in which two of the movable devices, namely the movable filling devices 11 and 12, operate.

The most forward of the lamellae is located below the filling device shown on the right in FIG. Bantramera A, B, C...
- The state when F is reached is shown at the top of Figure 8. The same applies to the filling device 11, below which the lamella D is located. Two charges'@
If the devices start their operation at this time, they will start filling the two cones located below the device, namely the cones located in the hunting lamella 7 and D. do. After the end of the stop intercostal space, the handles 11 and 12 are moved to the position indicated as "2" in FIG. Continue to operate. Status "2"
'', the filling of the wafer in lamella D also ends, which is indicated by the dashed line on the lamellae A and D in the figure.

Devices 11 and 12 then move one step to the left and at the same time the band moves one step to the right.

, devices 11 and 12 are located above lamellae F and C. Therefore, filling of wafers over them is started and continues during the transition from state "3" to "4". When this state ends, the wafers in lamellas F and C are also filled as shown.

It can be seen that the two devices 11 and 12 from the next state ``5~IOJ assist each other so that each of said devices alternately fills the wafer rows. However, if located in lamella B in FIG. Empty lamellae also occur when the wafer is not filled and a manufacturing interruption occurs.

If the devices 11 and 12 are arranged at a distance corresponding to one step, it is understood that the devices 11 and 12 fill alternating rows of wafers. However, in reality, it is difficult to closely arrange two filling devices because the current filling devices take up a space in their width direction that is wider than the distance corresponding to one pitch, ie, a step of the hand. In the figure, the mutual distance between the two filling devices 11 and 12 and the mutual distance between the two injection devices 9 and 10 correspond to three pinches or steps.

However, it will be understood that the same effect is obtained with other distances between two such devices corresponding to unequal numbers of steps.

Recognizing that the illustrated operating device is easily interchangeable with other operating devices, it can be used in conjunction with other operations instead of the production line shown in FIGS. 1A and 1B. For example, reference is made to the production of ice cream of the type in which the ice cream is placed between two flat wafers. In this case, a row of wafers is placed on the lamella of each conveyor hand during the first operation. This operation can be performed during a period of rest of the hand.

The ice cream is then applied to the wafer by means of two filling devices as described above, after which the placed ice cream is provided with decoration material, which can be done during a rest period. The cover wafer is placed by the following operating device, which can also be carried out during the rest period. For example, reference is made to a manufacturing example in which a cup has to be filled with alternating layers of jam and ice cream. in this case,
Cup positioning can be performed during one stop period used for one star jam positioning. Ice cream filling is then performed using the double filling device as described above.

If necessary, this operation can be carried out after placing the layer of Whinop cream during one stop jIJ1. Next, we will adjust the lid of the Q-cup, but this operation can also be performed during the Ichistop Market period. Finally, the lid is fixed, but this operation can also be performed during the stop period.
